Spinks can definitely embarrass Wilder as he has beaten a tall guy albeit one of the downturn, hes on just a different plane of existence in terms of skill. But the problem of Spinks being a career LHW converting to HW Wilder was never the biggest Heavy but he could definitely put more weight on and be effective with than Spinks could and he has that right hand. So factoring that I'll say a 75 to 80 percent chance for Spinks and a 20 to 25 percent chance for Wilder
